This invention relates to'journal'box'pacldng ferrailway cars andparticularlyfor freight kcars havingia journal box for oil which is fedto the bearing by the'w'icking action of -the packing.

An object is to Lprovide a textile packing pad for vthe above purposehaving novel and'improved'characteristics Another object is to providesuch a pad made from textile products, which has Aimproved wickingproperties, retains its form and resilience after long periods of use,effectively utilizes all of Ythe oil in a standard journal box, and iseasily inserted or removed.

Other objects and advantages will be apparentes the nature of theinvention `is more fully disclosed.

The invention will be better understood from the following descriptiontaken in connection with `the accompanying drawings in which a vspecific.embodiment has been set forth for purposes of illustration.

In the drawings:

Fig. .1 is a perspective view of ajournal box pad embodying the'present-invention;

Fig. 2 is a transverse vertical section through a journal box showingthe present pad in place; Fig. 3 is a longitudinal section takenvon'theline 3-3 of Fig. 2;

Fig. 4 is an lenlarged fragmentary section .showing the construction ofthe pad;

Fig. 5 is a detail view illustrating the yweave of the pad; and

Fig. 6 is a perspective view of a wicking -plug `used .in the presentpad.

Referring to Figs. 2 and 3 the invention is shown in connection with ajournal boX 10 for oiling a journal 11 on which a car 'frame 12 issupported b'y a bearing 13. Thejournal box 10 includes wallsforrniug anoil reservoir and an end door 16 through which the packing Ais i11-serted or removed. The journal box is of a standard type commonly usedon freight cars.

The packing pad in accordance `with vthe present .inven- Lion comprisesa woven fabric backing which is adapted to yconform vto the contour ofthe journal r11. This 'backing 20 may be made in one or more plies. Asshown in Figs. 4 and 5 the backing consists of two plies, each formed byinterwoven warps 21 and llers 22, the two plies being bound together bybinder warps 23.

It will be noted that the upper exposed surface of the backing 20includes ridges 25 where the Warps 21 pass :ver the fillers 22 anddepressions or recesses 26 in the ipace between fillers. Thesedepressions serve to receive and collect solid particles or dirt whichmay be present ind would otherwise injure the bearing or contaminate yheoil. The dirt thus collected on the upper surface of :he backing 20 maybe removed from time to time by :leaning the pad.

The side edges of the backing 20 are provided with `,tilfening inserts27 which may be made of textile woven is felted padding. These inserts27 provide a sufficient Mayl,

l bottom of such box.

Re. 24,643 Reissued Apr. 28, 1959 ICC'I thickness and body'for the upperedges of the backing' 20 to engage-the under surface of the bearing V13for positioning the pad and also to prevent the edges ofthe backing frombeing pinched between the bearing Band the journal 11.

In use the wear between the upper brass bearing13an`d the railroad carjournal 11 embeds the journal deeper-in the bearing and leaves aconsiderable opening at the two lower edges of the brass bearing. It maybe as muchas 1/a"'away from the journal surface after one -years wear.

The prior method of using yarn waste for lubricating purposes causesyfires when loose threads 'of oilso'altttd cotton get into thiswedge-shaped opening. This loss of a bearing in railroad parlance iscalled a wasteegrabf By .sewing the reinforcing strip 29 onto the upperedges of the present pad, `such wastegrab is eliminated.

The pad also includes a woven ply 30 which is com posed of warp yarns 31and fillers yarns 32 which is woven onto the backing 20 at spaced pointsand'extends downwardly in loops 35 between such points. A row of suchloops 35 is formed along the backing 20 as shown in Figs. 1 and 3. Aseries of such rows are displaced illerwis'e across the backing as shownin Figs. 1 and 2.

These loops 35 are of a length vto dip into the oil bath in the journalbox 10 and to extend substantially to vthe Plugs or pads 36 of absorbentor resilient material having wicking properties, such as feltcd woolbers or curled or crimped hogs hair or thelikc bonded into a spongy massby neoprene or the like are inserted in the loops 35. These pads 36are-of a size to completely till and be securely held by the individualloops and are of a length such that the plugs 36 in adjacent rows ofloops are in loose contact andserve to shape the backing to the sectionof the journal 11 when in place in vthe journal box 18. The plugs 36 maybe made wedge-shape for fitting and holding the backing in place'. Theloops of each row are spaced apart to leave a space for oil therebetweenand the loops ofadjaccnt rows which extend radially of the journaldiverge at an angle to leave 'a'wedge-shaped'ol space therebetween. Ahand loop 40 it attached t'o a pair of the end loops to provide a handleby which the 'entire assembly can be pulled out of the journal box'andhandled as a unit.

The loops 35 and backing 20 are made from 'yarn having wicking andnon-carbonizing properties, for example spun Daeron, a polyester rfiberhaving a basisfof polyethylene terephth'alate, so that the oil in thejournal box 10 is absorbed yby the plugs V36 and loops 35 transferred bywicking action to the backing 20 by which itis applied to .the journal11 for lubrication purposes. The

lubrication effect continues, `even after all of the 'free oil has beenabsorbed and in fact until all 'of the oil has been fed by the wickingaction of the loops and backing onto the journal.

A prevalent objection to the use of cotton waste is the formation of anoxide lm on .the journal, composed partly of some of the softer metalfrom the brass stationary bearing in combination with carbon fromcharred parts of the cotton and sulphur molecules from the oil. Thisbuild-up on the surface of the steel journal increases the coefficientof friction and therefore the heat generated during motion. It alsopeels oif as a scale or glaze onto the cotton pad and stops the ow oflubricating oil from the pad to the journal.

The present pad eliminates this build-up of oxide film by using Dacronwhich does not carbonize and can withstand high temperatures and doesnot serve as a bond for the molecular chain involved in creating thisoxide film.

The textile pad can be readily removed and replaced and the plugs orpads 36 can be removed from the loops 35 and renewed when necessary.

, 3v `The depending loops and plugs engage the bottoms o the journal boxto hold the backing in pressure engagement with the journal.. Theconstruction is such .thatrthe pads 36 retain their resilience so as tomaintain f pressure on the backing for-the entire life of the pad.

. .The felted wool plugs are highly absorbent. vThe bonded hogs hairpads are somewhat less absorbent but have great resilience and retainthis resilience throughout their life. Such plugs serve to maintain thebacking in pressure engagement with the journal. A combination of bothtypes of plugs may be used if desired.

The backing may be woven in one piece. or may be `woven in plies andsecured together. The backing is shown as formed in strips, eachcarrying a row of loops .35 and stitched together by rows of stitches41. It may .be woven as a single piece however if desired.
